1. An upper-layer base station that forms an upper-layer cell in a wireless communication system in which lower-layer cells are superimposed onto the upper-layer cell, comprising: an upper-layer wireless section configured to achieve communication with at least one wireless terminal that is present within the upper-layer cell; an upper-layer inter-station communication section configured to achieve communication with lower-layer base stations that form the lower-layer cells; and an upper-layer control section configured to, via the upper-layer inter-station communication section, command any one of the lower-layer base stations that satisfies preconditions for making a connection in order to communicate with a wireless terminal that is currently performing communication to switch from a power saving mode to a normal operation mode, wherein, if, based on the operating frequency and on the position information relating to the wireless terminal that were acquired by communicating with the wireless terminal, one of the lower-layer base stations is judged to be capable of dealing with the operating frequency of the wireless terminal, and the wireless terminal is judged to be positioned within the lower-layer cell of that lower-layer base station, then the upper-layer control section determines that the lower-layer base station is a lower-layer base station that satisfies the communication connection preconditions. |
